What is the process to download EMF Compare source, make changes, and build it on Eclipse?

I saw the EMF Compare/Contributor Guide on the wiki.

I cloned the git repo for EMF Compare, and imported the project into my workspace like the wiki says. But when I build the project I get lots of dependency issues and the MANIFEST.MF files all have some bundle that cannot be resolved.

Also how does one build the project?

I also recently tried to check out the 1.3 branch and run, mvn clean package -Pindigo But I run into lots of errors:

I think one of the major problems is the Manifest file. There are lots of unsatisfied constraint errors. How do I make sure all of the imported packages are satisfied?

I have started to search the build file for the bundles that are missing. I was able to find one Google.commons missing, That is found at: code.google. com/p/guava-libraries/. Just download and install guava.jar.
I am working on Papyrus dependency problems now. I cannot install the jars from the download pages because I keep getting dependency not satisfied errors... I do not know how to fix that.
